I'm not American but I guess the same applies everywhere...I just call it "low level populism".

Being able to criticize a political system or orientations is essential to any democracy IMHO.

Uh there are some things which you can legitimately say that they are UnAmerican and/or borderline treasonous.

Selling military equipment to a country where in our laws it is illegal to sell stuff like that to especially when they are supplying and training people whom go on to attack our troups is a good example.

Specifically I'm bringing up General Electric which so happens to be the Parent Company of NBC and MSNBC.
